Abstract
The explosion of enhanced applications such as live
video streaming, video gaming and Virtual Reality calls for efforts
to optimize transport protocols to manage the increasing amount
of data traffic on future 5G networks. Through bandwidth
aggregation over multiple paths, the Multi-Path Transmission
Control Protocol (MPTCP) can enhance the performance of
network applications. MPTCP can split a large multimedia flow
into subflows and apply a congestion control mechanism on
each subflow. Segment Routing (SR), a promising source routing
approach, has emerged to provide advanced packet forwarding
over 5G networks. In this paper, we explore the utilization of
MPTCP and SR in SDN-based networks to improve network
resources utilization and end-user’s QoE for delivering multime-
dia services over 5G networks. We propose a novel QoE-aware,
SDN-based MPTCP/SR approach for service delivery. In order to
demonstrate the feasibility of our approach, we implemented an
intelligent QoE-centric Multipath Routing Algorithm (QoMRA)
on an SDN source routing platform using Mininet and POX
controller. We carried out experiments on Dynamic Adaptive
video Steaming over HTTP (DASH) applications over various
network conditions. The preliminary results show that, our QoE-
aware SDN-based MPTCP/SR scheme performs better compared
to the conventional TCP approach in terms of throughput, link
utilization and the end-user’s QoE.
